Amardeep steel pipes and tubes are also known as EN 10224 Grade L290 Carbon Steel Seamless Tubes. EN 10224 Grade L290 Tubes are low-cost Low Carbon Steel Tubes with a maximum carbon concentration of 017% and a manganese level of 080% that are easy to form and shape. These pipes are made in accordance with EN specifications and are commercially known as cs pipes or ms pipes. Although carburizing can raise the surface hardness of low-carbon steel pipes, they are not as hard as high-carbon steel pipes.
